I I Like characters of reference refer to'simi larparts and portions throughout the several views of the drawings. r I

5 The supporting means of my pipe threading mechanism or means consists 1n one form 1 of a base 1, upright pipesections 2 and a head .3. The base member 1, as shown in the drawv ings, is. mountedon and above the running board at one side'of the vehicle or truck portin gpipe sections 2, said pipe sections This base meinberis provided with a ing 6.

8 at its opposite end.

being secured in the sockets 1 by means of set screws 5. The upper ends of the plpe sectlons are secured into sockets at the lower side of the head 8 positioned above the base member and also to the side of the vehicle body. The central portion of the head8 is provided with a hollow cylindrical portion 8" extending from end to end. At the opposite ends of the. portion 8 are mounted bearing bushings 6 in which is revolubly mounted the sleeve 7 carrying a chuck at its one end and a removable pipe guiding collar The sleeve 7 is retained longitudinally within the head by the chuck at one end and a pair of lock nuts or collars 9 near the opposite end, which nuts. or collars bear against the rear bearing bush- The chuck consists of a jaw carrying member 10 non-revolubly and "longitudinally fixed relative to the sleeve 7 by means of a lock nut member 11 a )luralit of 'aws 12 rea l y universal joint means on a bracket 20 secured ciprocally mounted in the jaw carrying member 10 in a radial direction, a screw member 18- and a drive gear 14. The aws 12 are provided at their front sides with transversely and slightly angularly extending teeth 12, which extend beyond the front side of the jaw carrying member 10 and are adapted to be engaged by a scroll or spiral ridge l8 provided at the back or inner side of the scroll member 18, said scroll member being positioned against the front side of the jaw carrying member by the lock nut member 11., shown best in Fig. 1. The scroll member 18 is provided at its front side with a number of lugs l8 having radially extending holes for receiving a suitable tool for rotating the scroll member and thereby radially and si multaneously adjusting the jaw members 12.

The gear 14 is secured to. the back side of the jaw carrying member 10 and is in the form of a bevel gear. This bevel is driven by a bevel pinion 16, which is secured to the oneend of a shaft 17 extending downwardly at an angle toward the vehicle body, and is revolubly mounted in a journal 8 carried by the head 8, The opposite orlower end of theshaft 17 is connected, by means of a universal joint means 18, with another shaft 19 revolubly mounted at the end adjacent the on the outside of the vehicle body and at its opposite end on a bracket 21 preferably mounted on the main frame of the vehicle. At the end of the shaft 19 extending diago nally into the interior of the vehicle body is mounteda bevel gear 22, which meshes with and is'driven by a bevel pinion 28. The pertion of the shaft 19 between the brackets 20 and 21 may be covered by a tubing-'24, as

- shown. The pinion 28 is mounted at the one end of a shaft 25 also revolubly mounted in the bracket 21 at a right angle to the shaft 19. I The opposite end of the shaft 25 is connected 29 revolubly mounted in the transmission casing of the vehicle. On this shaft 29 is slidably mounted a gear 81, which is adapted to mesh with a gear '82 continuously rotated. within the transmission casing 80 when the transmission mechanism is connected with the power plant of the vehicle.

The gear 81 may be shifted into mesh with the gear 82 by means of a gear shift rod 88 reciprocably mounted in the transmission casing and connected at its'one end, by means of a rod 84-, with the oneend of a gear. shift lever 85 pivotally mounted intermediate its ends on the frame 86 of the vehicle.

The clutch lever 87 for connecting and disconnecting the transmission mechanism with and from the power plant of the vehicle is preferably mounted on the same pivotal axis with the gear sl'iift lever 85 and is pivotally connected at its one end, by means of acable 88, with an arm 89 connected with and extending in the opposite direction from the main arm of the clutch pedal 40 ofthe vehicle. i

i V'hen desiring to connect the chuck with the power plant, the lever 87 is shifted in a clockwise direction, the lever 85 shifted in a counter-clockwise direction, and the lever 87 released.

At the one side of the head 8 and near, the opposite ends thereof are provided hollow bosses 8 and 8 in which is reciprocally mounted a guide member 41 in the form of a pipe section, which is provided at its forward end with a socket member 42, which may be in the form of elbow, the side opening of which is provided preferably with a pol gonally shaped recess 4-2. here noted that the head 8 is preferably braced relative to the body of the vehicle by means of a bracket portion 8 extending wardly from the boss 8, as shown. At the opposite side-of the head 8 and near the opposite ends thereof are provided other hollow bosses 8 and 8 in which is removably positioned a guide member 48, also preferably in the form of a pipe section.

j The die for cutting the threads on the pi e P, which is held in position by the chuc is preferably cutting members rable in a radial direction, so that when the thread is cut on the pipe, the thread cutting members .vardly from the cutting position, permitting the die to be shifted clear of of the pipe while the same is revolving. This die is of conventional construction and consists essentially of a housing 4a in which is shiftabiy mounted in a radial direction a piurality of thread cutting members 45, their inward and outward positions being deter- It will be may be released and. shifted out-' the threaded end l camsv 46 operatingin slots in the thread cutting members and controlled in any suitable mam-456 mined by the positions of spirally arranged extending bosses 44 and 44 in the former of which is secured a plug having a cross secdially means of tion,

tion corresponding with the recess in t the socket member 42, and in the opposite boss 44* of whichv is secured'ahandle member 49 for handling the one orfree side of the die and for non-rotatably guiding the same against the under side of the guide member 48, as shown in Fig; 2. Since the die doesv not rotate, the thread cutting members and pipe may be readily oiled through an oil hole, 44 from the upper side of the die without inter ruptiiig the thread cutting operation. When desiring to cut a thread, the thread cutting members 45 in their inward orthread cuttingpositions; the die is then placed with its plug 48 inthe recess 42 and with its handle. member 49 agaiiist'the under side of the guide member 43; the die is then shifted toward the end of the pipe P extending beyond the front side of and revolving with the chuck. When the thread is of suflicient length, the thread cutting members are released and expanded rathe lever 47; the die is then shifted away from the chuck, lowered at the end nearest the operator and removed from the socket member 42.

When not operating the pipe threading means, the guide members 41 and'43 are re-I moved so that the same do not interfere with the normal operation of thetruck or so that the same cannot be locked. i
